Lab Tests You Should Ask Your Doctor For (Or Order Yourself)

This post may contain affiliate links.

blood tubesI am often asked by both clients and blog readers what general lab tests I recommend for tracking overall health, particularly when a person does not have any significant health issues they are trying to monitor.

Sometimes it’s hard to know what tests are worth running to get a good sense of how your body is operating and to catch any issues before they cause symptoms, such as low thyroid activity, borderline anemia, or elevated blood sugar.

I find that many doctors don’t run routine comprehensive (i.e. functional) blood work unless asked, but most are happy to order a variety of tests to get a snapshot of your general health if you ask them to.

And if you don’t have a doctor who is willing to run labs for you, there are options for ordering your own labs and paying out of pocket (unless you live in a few specific states like NY, NJ, and RI).

In this post, I’ve compiled a list of recommended blood tests that anyone who wants to monitor their health might be interested in getting done, and give a brief explanation as to why a person might want to know those particular values.

If you want to know more about which tests would be important for your particular needs, consider working with me one-on-one so we can personalize your plan.

Recommended Basic Lab Tests

  • Comprehensive Metabolic Panel –  provides an overall picture of your body’s chemical balance and metabolism.
  • Lipid Profile – gives an overall picture of cardiac risk and can help determine if dietary changes are necessary, includes:
    • Total cholesterol
    • HDL and LDL
    • Triglycerides
    • If History of Heart Disease: NMR profile, ApoB
  • C-Reactive protein (hsCRP) – one measure of general inflammation, if high can indicate possible autoimmune disorder, infection, and/or need for diet change
  • Blood Sugar Profile – gives an overall picture of the body’s use of glucose, may indicate a need to change dietary carbohydrate intake (either increase or decrease)
  • Thyroid Panel – helps evaluate thyroid gland function and diagnose thyroid disorders
  • Vitamin D – I consider the optimal range to be between 30-50 ng/mL, though there is some controversy here. Low vitamin D levels are often found in patients with autoimmune disease, poor immune function, bone disorders, and mental health issues.
  • Complete Blood Count – includes iron, ferritin, transferrin saturation %, and information about the size and color of the red blood cells. Can identify anemia, infection, elevated immune activity, B12 deficiency, and/or iron storage diseases
  • Vitamin B12 and Folate Panel – Can help diagnose a nutritional cause of anemia or neuropathy, may  indicate need for diet/supplement changes, may be related to methylation defect such as MTHFR


Those are my basic recommendations! These are generally the labs I ask my patients to have done before their appointments with me, and I personally ask for these when I have my annual(ish) checkups.

If your doctor will not order these tests for you, most people can order tests online if they are willing to pay out of pocket. This is the website that I most commonly send patients to if they’d prefer to order their own labs. (Note: some states have different rules about ordering your own labs.)

  1. you say “If History of Heart Disease: NMR profile, ApoB”
    Why not if no history of heart disease – I thought LDL-P was more important than TC?

  2. Hi Laura,
    I live in the UK and as you know we have the NHS here. I doubt very much if our GP’s here would even consider doing blood tests unless a patient had a general illness. Would you still recommend asking them for a routine blood test? Can you recommend any online places here in the UK for lab tests? Many thanks.

  5. I have all the symptoms of a thyroid problem, and my Dr. first checked the usual, TSH and free T4, plus antibodies, which all turned out OK. She is willing to add on the other testing, but said she is not sure what to do if my T3 numbers are off. Is there a good resource I can pass on to her? She’s a great Dr. but not trained in functional mediicine, but is very open minded.

  6. Why is not available in certain states anymore? I live in NJ, can I request the test in another state. Even though, I don’t live in that state?

  7. I have HPAD and feel like I would never dare to leave the house in the morning without eating. I also have the reaction where my blood pressure drops when my vein gets punctured and I’ve fainted before on non fasting blood tests even before I had adrenal issues or anxiety which I do now. How could I ever do this? I’ve done blood spot tests before for thyroid I wonder if it’s possible for other things. I have no aversion to needles it’s just a physical reaction.

  8. I am hypothyroid, had my thyroid removed because of cancer. Do the “Functional” Ranges for all thyroid blood work apply to me as well? I still don’t “feel” normal – I feel fatigued, don’t sleep well, adn my metabolism is as slow as a turtle!! Is there something else I should be asking my doctor to check?

  9. Are there any additional tests you run for a young client (18) that hasn’t had her period in 2 years? In recovery, slowly gaining, but still no period? Is there anything blood work wise that would be good to know/eliminate for hopeful return of Her period?
